摘要

针对高压XLPE电缆缓冲层烧蚀故障给电缆安全运维工作造成较大影响的问题

提出基于特征气体的缓冲层烧蚀故障检测技术。通过搭建XLPE电缆缓冲层模拟烧蚀实验平台及电缆真型实验平台

研究电缆缓冲层烧蚀故障所产生的特征气体及其烧蚀特性

重点关注缓冲层受潮率、缓冲层厚度、缓冲层施加电流有效值对缓冲层特征气体的影响

结果表明：缓冲层施加电流大小是影响特征气体浓度的最主要因素

且缓冲层在受潮条件下更易发生烧蚀

缓冲层厚度越薄越容易发生烧蚀。对两条出现缓冲层烧蚀故障的电缆进行实际应用测试

对缓冲层气体成分进行分析可以诊断出该电缆段是否发生缓冲层烧蚀故障及故障严重程度

验证了基于特征气体的缓冲层烧蚀缺陷诊断技术具有可行性。

Abstract

Aiming at the problem of high voltage XLPE cable buffer layer ablation faults causing a big impact on the safe operation and maintenance of cables

the buffer layer ablation fault detection technology based on characteristic gases is proposed. By building the XLPE cable buffer layer simulated ablation experimental platform and cable true type experimental platform

the characteristic gases and their ablation characteristics generated by the cable buffer layer ablation faults are studied

focusing on the buffer layer moisture rate

the buffer layer thickness

and the buffer layer applied current RMS value on the buffer layer characteristic gases. The results show that the magnitude of current applied to the buffer layer is the most important factor affecting the concentration of characteristic gases

and the buffer layer is more prone to ablation under moisture conditions

with smaller suffer layer thickness being more prone to ablation. Through the practical application of two cables with buffer layer ablation faults

the results show that the analysis of the buffer layer gas composition can be used to diagnose whether or not buffer layer ablation faults have occurred in the cable segment and the severity of faults

which verifies the feasibility of buffer layer ablation fault diagnostic technology based on characteristic gases.
